I have a site with 10 APs in a dense urban location. I was able to have an onsite person do a good survey with an Ekahau Sidekick. There is massive 2.4 interference as suspected. However we were able to get a good 5Ghz channel mapping scheme so there is little to no interference.
So after setting up a dedicated 5G SSID, we ran through our key use case which is a Facetime call on an iPhone walking through the location at a fast walk.
We confirmed we have excellent primary signal strength and secondary signal strength with the survey, as well as clean channels.
I was feeling confident once we got to a dedicated 5G SSID that things would be better. It turns out that despite our dedicated 5G SSID, the subjective performance is better on the 5G and 2.4G SSID.
We had some mixed capability APs - some Ruckus R610 along 3 newer R550. Once we turned off 802.11ax - that helped our 5G only SSID, but still was not performing well enough (roams were very rough).
802.11k and r are turned on.
Upon further digging, I see iOS devices stubbornly hang on until -71 db. There are some very poorly placed placed APs but we do have sufficient total number of units to support signal strength.
My challenge now is to try to pin down what is preventing the iOS / mobile device from not roaming well. Watching Joel Crane demo on Tonic I saw a hint that maybe there was going to be a device follow feature on Tonic. I’m completely new to the tool. I’m hoping for anyone to give me some advice on how to nail down what the roaming issue could be.
Generally, clients not moving will associate to the appropriate AP and will work well when not in motion.
I was hoping I could pin the problem on the huge amount of 2.4 interference but with dedicated 5G SSID that seems to offer WORSE performance, something else is going on.
Any tips, tricks or hints massively appreciated. Anyone have feedback implementing Sapphire Eye from 7signal?
